A 1.000-g sample of a sweetening agent containing soluble Saccharin (MM=205.17g/mol) was analyzed using the Volhard method as follows: Step 1: Sample was dissolved in distilled water and treated with 10.0 mL of 0.05M AgNO3. Saccharin-Na + Ag+ → Saccharin-Ag (s) + Na+ Step 2: The solid, Saccharin-Ag (s), formed was filtered off and washed with water. The filtrate and washing were collected quantitatively. Step 3: Titration of the filtrate and washings required 4.6 mL of 0.04M KSCN. KSCN + Ag + → AgSCN (s) + K+ Calculate weight % saccharin in the sweetening agent sample.
